Saint-André-sur-Orne (French pronunciation: [sɛ̃.t‿ɑ̃dʁe syʁ ɔʁn] ⓘ, literally Saint-André on Orne; named Saint-André-de-Fontenay until 1911) is a village in the Calvados department in the Normandy region in northwestern France.

The village's history is closely linked to the Saint Stephen abbey "Abbaye Saint-Étienne-de-Fontenay" founded on his land of Fontenay by Raoul Tesson around 1047 under the patronage of Duke William of Normandy (before he became King of England following his victory in Hastings in 1066) and which survived until the French Revolution at the end of the 18th century.

The village witnessed the expulsion of many schoolchildren from the "Maison du Clos" by the Nazi army during World War II, but the marching children were then rescued by Allied soldiers.

[3] The village was finally liberated in July 1944 by Canadian soldiers, many of whom died in this fierce battle, hence the street names of "Royal Black Watch" (the Montreal-based regiment) and the village's main street "Rue des Canadiens".

Their bodies are buried in the Bretteville-sur-Laize Canadian War Cemetery in the nearby village of Cintheaux.
